NUT-LOCK.

Specification of Letters Patent.

Patented Aug. +1, 1914.

Application filed October 14, 1913. Serial No. 795,040.

To all whom it may concern:

Be it known that I, Wnrri-inm H. Enwiinos, a citizen of the UnitedStates, residing at Tnmina, in the county of Montgomery and State ofTexas, have invented certain new and useful Improvements in Nut-Locks,of which the following is a specification.

This invention relates to new and useful improvements in nut locks.

The object of the invention, is to provide adevice of the'charaeterdescribed, whereby a nut maybe securely locked upon the bolt upon whichit is threaded, against accidental displacement therefrom, and is so eonstructcd that, when a wrench is applied to the nut for turning the some,the locking device will be disenga ed, so that the'nut will be readilyturned but at all. other times the nut will be locked against turning onthe bolt.

A further feature of the invention resides in the provision of a deviceof this character which will be cheaply and easily constructed and whichwill not readily get out ofrepair.

With-the above and other objects in view, the inventionhas particularrelation to oer-- tain novel features of construction, arrange-- ment ofparts, and use, an, example of which 'is given in this specification andillustrated drawings, wherein-v Figure 1 shows a side elevation of thebolt, showing the nut locked thereon. Fig. 2 shows a side elevation ofthe bolt, showing in the accompanying the nut in section and the lockingdevice applied thereto, and Fig. 3 shows an end view .of the boltshowing the locking device in plan view.'

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, the numeral1 refers to a bolt, one end of which carries the usual head 2, and theother end of which is exterior-1y threaded to receive the not 3. Thisnut is interiorly threaded in the well known manner; but the assagewaythrough the nut is enlarged at its outer end, fr t ing an anrmlar space4 around the OXtPQr ie end of the bolt 1 and extending from this spacethrough the cur rounding wall-tit the but an orifice 5 through which thestem of the Y-shaped member 6 passes. This member; has two bolt 1., asshown in Fig. 3 and the free ends of said prongs have inwardly extendingcatches 7, 7. lhe periphery of the free end of the bolt 1 isprovided-with a plurality of lengthwise slots 8 and the catches 7normally engage in two opposingslots and. thereby lock the nut againstturning, relative to the bolt. The-prongs 6 are formed of strongflexible material and when a wrench is a plied to the nut, it will pressagainst the outer end of thestem and force it inwardly toward the bolt,causing the bolt to wedge between the prongs thereby forcing; the freeends of said prongs outwardly ahd disengaging the catches 'i' from theslots 8 and permitting' the nut'to turn on. the bolt. The annular spacet is of a suilicicnt width to ermitthis movement of the prongs 6.

hen the wrench has been removed. from prongs which embrace the free endof the l the wit the resistance of the prongs 6' against the boltwill besuliicient to force the stem outwardly to its original position and thecatches 7 will again scat against thebolt and when the nut is turned asufiicient distance to bring said catches opposite the slots 8, thecatches will then engage in said slots and the out will be lockedagainst further turning on the bolt.

What I claim is t 1. In a device of the character described, thecombination with a bolt and a nut threaded thereon, of a Y-sh'epedmember formed of a stem and two flexible prongs, the stem havingslidable engagement with the nut and the prongs embracing the bolt, thefree ends of said prongs having detaclr able engagement with the bolt.

2. A device of the character described, comirising a bolt, one end ofwhich is out- Wltl't' iy threaded. said end having a plurality oflengthwise slots arranged around the,

also having; an orifice extending from said annular space through thewall thereof, a
